Fig. 12 is a section on the line I2I2 Vof Fig. 11. In the embodiment illustrated in Figs. 1 to 5 inclusive, the embodiment of the lighting xture present instance is illustrative of the twofhundred watt lamps extensively used.

To cover the hickey 2, conduit 3, lamp socket 4and neck of the lamp 5 in the present instance,

bodimentof :the present]in'vention;`` c55 there is provided a covering having the canopy 5 consisting of the outwardly flaring hollow base portion 1, the upper outer edge of which engages the face of the ceiling I and from the inner lower end of which there extends `the thimble portion 8 through which extends the conduit 9. The length of the conduit 9 is preferably predetermined to correspond to the distance between the lower edge of the hickey 2 andthe disc I0 disposedat the upper' end of the socket 4 and in which case the socket 4 supports the disc I0 'and the disc II! in turn supports the conduit 9 in position on'the conduit' 3.

The canopy E in "turn is positioned against the ceiling I by the ring II `mounted on the conduit p9 due to the set screw I2 extending through the I4 is preferably provided with three small slots` I'I which are cut throughthe .ilange I6 and up intothe outer wall of the cover `I4 asshown in Fig. 1.

The main portion of the present invention will now -be described. It consists essentially of the yshell I8 having a plurality of beads or annular steps, four being shown in the present instance to wit, I9, 20, 2| `and 22. These steps I9't0 22 inclusive are preferably formed as shown in an inwardly curved surface of the shell I8. The

`lower end of the shell I8 in the present instance terminates in a helmet shaped inverted dome portion 23,

nected by three sets of connecting devices 21 and ball chains 28. essentially of a block 29 composed preferably of a translucent plastic material which is preferably provided with an upper face 39 conforming to the inner face of the flange 25, and outer face 3| conforming to the intervening portion Each connecting device consists mediate portion 32 and from there onto the outer face of the shell I8.

Obviously the angle of the inner face of the flange 25 and the inner face of the intermediate portion 32 relative to the lamp 5 will depend upon the curvature or inclination of the outer face of the shell I8 in` order to produce the desired lighting effect on the outer face of the shell I9.

It is of course obvious that the bulbous portion 41 of the lamp 5 may be silvered or provided with a metal cap, such as the cap 48 having an inner reflecting surface in the interest of indirect lighting without departing from the spirit of the invention.

In the embodiment shown in Fig. 6, the lower end of the socket covering 49 corresponding to the socket covering I4 in Fig. l is connected to a fixture portion having a plurality of shell mem- 32 of the rim 24 and a lower face 33 conforming to the inner face of the flange 28, the shoulder 34 preferably being disposed in alinement with the inner edge of the flange 26.

Each of the blocks 29 in addition is provided with a slot extending from its inner face 36 42 is preferably inclined to form a. right angleor less with the line of pull of the ball chain 28. A ball chain 28 as shown in Fig. 1 is connected to the finger 42 and lower edge of the cover I4 in the well known manner by having it pressed into the recess 43 and recess I1 as shown.

The upper flange of the rim 24, see particularly Figs. 2 and 3 is preferably provided with three recesses 44, 45 and 4B conforming in width to the bers and rim portions. When two shell members, such as the shells and 5I are used, the upper shell consists of an annular member having a rim 52 at its lower end to cooperate With the shell 50 and a separate rim 53 is provided to cooperate with the shell 5I. The shell 59 in this embodiment is provided with one step formation 54 dividing the shell 50 into an upper annular area 55 and a lower inverted helmet shaped area 56.

In this embodiment too, there are preferably provided three ball chains 51 similar to the ball chains 28 of the embodiment illustrated in Fig. 1 connected to the lower end of the socket cover 49 by means of recesses as shown in Fig..1 and connected to the projections or fingers 58 of the connecting devices 59, similar to the connecting devices 21, secured to the outer upper edge of the shell 59 and to the rim 52 similar to the rim width of the shank portions 4I of the metallic',

clips 39. vices 21 and ball chains 28 in place, the ball chains are first connected to the connecting devices 21 and to the lower end of the socket cover I4, then the rim 24 is slipped up adjacent the cover I4 and then the outer edge portion 31 of the shell I8 inserted into the recesses 35 of the blocks 29 grouped together as shown in Fig, 3. The annular rim 24 is thereupon pulled down over the blocks 29 and the edge of the shell I3 and thereupon the blocks 29 separated until each register with one of' the recesses 44, 45 and 46.

The canopy 6, ring II, conduit 9, cover I4, rim 24 and shell I8 may be of any suitable decorative substance, such for instance as aluminum, it of course being obvious that' the canopy 6, cover I4, rim 24 and shell I8 may consist of spun or drawn aluminum.

Preferably the inner upwardly extending face of the shell I8 is polished to fO-rm o-r provided' with a reflecting surface and the inner faces of the rim 24 similarly polished to form or otherwise provided with a reflecting face for the purpose now to be described. The light rays from the lamp 5 may of course be freely directed upwardly against the ceiling I to produce indirect light rays. In addition, the light rays, see for instance the dash and dot lines of Fig. 1, pass from the lamp 5 first to the inner face of the flange 25, then to the inner face of the inter- `In order to connect the connecting de-` discussed in the embodiment illustrated in Fig. l.

The rim 53 on the other hand is provided with three blocks 69 having upper and outer faces conforming to the inner faces of the rim 53 and slots EI conforming in thickness and shape gc: the upper outer edge portion 62 of the shell `To assemble the several parts of this fixture,

the rim 53 is first slipped in place adjacent the cover 49 either before or after the ball chains 51 are connected to the socket cover 49 and their connecting devices 59, then the blocks 69 slipped in place on the outer edge portion 62 of the shell 5I, then the rim 53 slipped down over the blocks 69 and then the blocks 60 equally spaced from one another. On the other hand, the rim 53 may be secured to the shell 5I before slipping it up adjacent the socket cover 49. Thereupon the connecting devices 59 are grouped together and slipped on the outer edge portion 63 of the shell 50 and then the rim portion 52 slipped over the connecting devices 59 and thereupon the connecting devices 59 equally spaced from one another as explained with regard to assembling the parts illustrated in Fig. 1.

With this embodiment, it will of course appear that the angle of the inner faces of the rims 53 and 52 relative to the light rays coming from the lamp 64 will depend upon the curvature and e inclination of the outer faces of the shells 5I and `vices 21 shown in Fig. 1, which are mounted in the rim 10 secured to the outer upper edge of the shell 1| by such connecting devices 69.

The outer face of the shell "Il has a different decorative design than that shown in Fig. 1 and has provided at its lower end a chain connection 12 to which there is in the present instance attached a decorative ball 13 composed for instance of glass or other light reflecting substance.

Preferably in the present instance, there extends from the ceiling 66 an annular shell 14 spaced from the outer edge of the rim 10 to cooperate with the rim 10 and shell 1| to form a ceiling fixture.

In the present instance, some of the light rays from the lamp 65 will of course be directed upwardly against the ceiling inside the shell 14 and also be directed against the inner face of the shell 14\ preferably formed into a reflecting surface and other light rays from the lamp E will be directed against the inner face of therim 'I0 to be` reflected against the outer face or decorative surface on the outside of the shell 1| and also onto the glass ball 13.

In the embodiment illustrated in Figs. 8 and 9, the suspended shell 15 conforms to an inverted six-faced pyramid with alternate triangular faces 16, 11 and 18 provided with an ornamental finish and the remaining triangular faces 19, 80 and 8| either provided with an ornamental finish or plain as indicated in Fig. 9.

The upper end portions 82 of the panels 16, 11 and 'I8 have each attached thereto a reflecting rim 83 similar to the reflecting rim 24 of the embodiment illustrated in the embodiment of Fig. vl. These reflecting rims 83 may be separate straight pieces as indicated in Fig. 9, each separately connected to the socket cover 84 by connecting means including ball chains 85 and connecting devices 86. Each rim 83 is provided with two notches 81 and 88 near its ends to receive the fingers 89 of the connecting devices 86, which fingers 89 are similar to the fingers 42 of the embodiment illustrated in Fig. 1 and associated with blocks 90 similar to the blocks 29 of the t embodiment illustrated in Fig. 1.

With this embodiment, it will of course appear that alternate faces will be illuminated in the interest of the ultimate decorative effect.

In the embodiment illustrated in Fig. 10, the invention is shown associated with a floor lamp in which the upright 9| has formed at its upper end a lamp socket to receive the lamp 92 with its bulbous end facing upwardly and the socket of the lamp provided with a cover 93 which is provided with slots at its upper end to receive the ends of the ball chains 94 connected to the fingers 95 of blocks 96 secured in a reflecting rim 91 formed at the lower edge of the shell 98, the shell 98 in the present instance being conical with its wide end at the bottom.

The outer face of the shell 98 in the present instance may be formed to produce a decorative effect or provided with a decorative surface as shown. Some of the light rays from the lamp 92 will of course be directed against the inner face of the shell 98 which may be provided with a refleeting surface to be directed downwardly and other light rays be directed against the inner face of the rim 91 which is provided with a reflecting surface, the angles of which rim relative to the lamp are such that the light rays will in turn be deflected onto the outer face of the shell 98 or the decorative effect on the shell 98. The blocks 96 of the connecting devices in the present instance are inverted as compared to the embodiments heretofore described and the shape of the same consequently slightly changed.

In other respects the connecting devices 96 and ball chains 94 are practically the same as those used with the embodiment illustrated in Fig. l.,

In the embodiment illustrated in Figs. 11 and 12, there is shown a Wall bracket 99 to which is connected a lamp |00 and a shell |0I to intercept the direct rays from the lamp |00. The outer face of the shell |0| is preferably provided with an ornamental effect either due to the configuration of the shell itself or to the ornamental matter secured thereto. Disposed along the vertical edges of the shell lill, there are provided the vertically extending rims |02 and |03 having refiecting faces to` receive some of the light rays from the lamp |00 and reflect them onto the adjacent outer faces of the shell |0|.

In the present instance, there are provided two blocks |04 and |05 adjacent the lower ends of the shell |0| and two blocks |06 and |01 adjacent the upper end of the shell |0| which are slotted to receive the end portions of the shell |0| and provided with outer faces conforming to the inner faces of the rims |02 and |03 to snugly fit in the rims |82 and |03 as illustrated.

It is of course obvious that the shell, as for instance the shell |8 of the embodiment illustrated in Fig. 1 may itself be constructed to present an outer ornamental configuration or else the outer face or faces of the shell I8, see for instance the outer faces of the shells 50 and 5| of the embodiment illustrated in Fig. 6V provided with ornamental devices to produce an outer ornamental effect, see also the shells of the embodiments illustrated in Figs. 7, 8, 10 and 11.

It is of course obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
